Alex has a PhD in earth sciences from the University of Cambridge. He has worked in polar tourism in the Arctic and Antarctic as an Expedition Leader and guide since 2011 for a variety of companies on a range of vessel sizes from 12 to 134 passengers. Prior to this career he worked as a professional yacht-master delivering vessels and training people to the RYA ‘Yachtmaster Offshore’ level. In 2014 he took part in the South Georgia Guideline Review of extended walks, acting as the IAATO representative. This gave him good insight into the GSGSSI view of tourism and need for industry standards for operating in this environment.

In 2018 he co-founded the Polar Citizen Science Collective, an organisation devoted to coordinating use of polar tour vessels for data collection and scientific research.

He is enthusiastic about training and skill development and this opportunity to merge his experience as a trainer and as a polar guide with what the PTGA has to offer. Alex is a passionate climber and skier and when not on ships can usually be found with skis or sticky rubber on his feet, and is currently working through the UK Mountain Training scheme.
